Just what comes to mind right now - Luis and Sofia (this journal; Eirena's sister) proooobably know each other, since Sofia does black marketeering too, although her stuff tends to be more "ethical" so that she can peddle it to the Alliance people who want the sort of things the Consortium sells but don't want any pesky ethical issues. Not-actually-friendly associates? Probably not rivals as such, but def. not friends either because lol, friends? Sofia does not know friends.
